I'm sorry, but I don't remember receiving an email from you...anyway,
I'm here!  :-)

I run Debian Linux here.  I use standard *nix utilities in the bash
script, and all are found in either /bin or /usr/bin on my system.  I
assumed (and maybe incorrectly) that these utilities are found in the
path of all *nix systems.  I won't add path statement to the script, as
there's no way I can come up with one that would work with everyone's
system.  I will, however, add a note to the script that the user ensure
that all the utilities used are available on the PATH.

If it's not recognizing the subject line, then procmail isn't passing
the subject line to the script.  You can see from the following snippet
of the script, that the journal entry is only created if the subject is
not passed to the script on the command line:

 if [ -z "$1" ]      #is filename blank?  if so, create journal entry
   FileName=`date +$WikiGroup.Journal-%Y%m%d`

FYI, ':' is stripped out by 'tr' down in the script.

That may a possibility.

Correct...pages added by my script will not show up in recent changes.
I, however, run another cron job that creates an index of these new
pages.  This essentially provides me with an 'inbox' of pages that I
want to edit/cleanup, at which time they are integrated into the rest of
my wiki.  You can also use PmWiki to locate orphaned files.

Sorry, the cronjob is necessary due to my using the bash script.  The
script creates the wiki pages with the ownership of the user who ran
.procmail on the message.  The pages, at that point, are readable by
PmWiki, but cannot be edited.  In order for PmWiki to edit the pages,
they must be owned by the user that runs your webserver (on my system,
Apache is run by www-data).  Therefore, the current setup requires the
ownership to be reset.

This was a quick hack, but I'll see about creating a PmWiki
plugin, which will take care of the ownership issues.  One reason I
haven't bothered to look into this so far, is that the script handles
'appending' data to the end of existing wiki pages, rather than replacing
all text on the page.  It will probably be at least a couple of weeks
before I have time to create a plugin with the same functionality.
